Sprockell is a Simple Processor in Haskell. It was originally written by Jan Kuper at the University of Twente. It has later been extended to allow multiple Sprockells to be run at once, communicating via shared memory. This version is internally been dubbed Smockell :-)

• Simple arithmetic
• Memory mapped I/O
• Branches / jumps
• Stack
• Local memory
• Shared memory

See the wiki.

Clone the repository, compile System.hs using ghc and run it from the command line. A (really) simple program runs and terminates.

Of course, you can compile your own program:

import Sprockell.System

prog = [ Const 6 RegA
       , Const 7 RegB
       , Compute Mul RegA RegB RegC
       , EndProg
       ]

main = run 1 prog

Where 1 is the amount of Sprockells you want to deploy.

ghc Program.hs
./Program

(Of course, this simple program doesn't produce any output. You can use Write RegC stdio for that.)

See the wiki on debugging.
